It would be better to move the fence away from you so the bit wouldn't be climbing and move the wood from right to left. Actually if the part is wide enough it would be better to put a fence on both sides of the board so it's not trying to pull away from the fence.So you cut a dado with a straight bit on the router table. The board is moved from right to left. Now say that the dado should be wider-- a second pass. You would like the dado wider with meat taken on the far side of the board--the side that was against the fence on the first pass. The board has a live edge, and the only side that can go against the fence is the same side that road the fence in the first place. Question: Do you move the fence closer to the bit for a wider cut; and now do you run that board from left to right so's not to "upcut?" TIA.
